Starter Cleaning, Inspection
and Testing
Cleaning and Inspection
1. Clean all starter motor parts.
2. Check pinion teeth for chips, cracks or excessive
wear.
3. Replace the drive clutch spring and/or collar if
tension is not adequate, or if wear is excessive.
4. Check that the brush holder is not damaged or is
not holding the brushes against the commutator.
5. Replace brushes that are pitted or worn to less
than 1/4” (6.4mm) in length.
6. Replace a damaged or excessively worn bushing
in the end cap.
7. Check the armature conductor (commutator bar
junction) for a firm connection. A poor connection
usually results in a burned commutator bar.
8. Resurface and undercut a rough commutator, as
follows:
CAUTION
Do not turn down the commutator excessively.
a. Resurface the commutator and undercut the
insulation between the commutator bars
1/32” (0.8mm) to the full width of the insula-
tion and so that the undercut is flat.
b. Clean the commutator slots after undercut-
ting.
c. Sand the commutator lightly with No. 00
sandpaper to remove burrs, then clean the
commutator.
d. Recheck the armature on a growler for
shorts, as specified in the following proce-
dure (“Testing”).
9. Open-circuited armatures often can be saved
where an open circuit is obvious and repairable.
The most likely place for an open circuit is at the
commutator bars, as a result of excessively long
cranking periods. Long cranking periods over-
heat the starter motor so that solder in the con-
nections melts and is thrown out. The resulting
poor connections then cause arcing and burning
of the commutator bars.
10. Repair bars, that are not too badly burned, by re-
soldering the leads in bars (using rosin flux sol-
der) and turning down the commutator in a lathe
to remove burned material, then undercut the
mica.
11. Clean out the copper or brush dust from slots be-
tween the commutator bars.
12. Check the armature for ground. See the following
procedure (“Testing”).
Testing
ARMATURE TEST FOR SHORTS
Check armature for short circuits by placing on growl-
er and holding hack saw blade over armature core
while armature is rotated. Recheck after cleaning be-
tween commutator bars. If saw blade still vibrates, re-
place armature.

Armature Tests for Shorts (Bosch)
ARMATURE TEST FOR GROUND
1. Set VOA meter to (R x 1 scale). Place one lead
of VOA meter on armature core or shaft and other
lead on commutator.
2. If meter indicates continuity, armature is
grounded and must be replaced.
